ABSTRACT:
A playback apparatus for precisely reflecting attribute information such as copyright information even in a special playback mode, such as reverse slow playback, fast playback and reverse playback. Encoded presentation data such as a video and audio is separated by a stream analysis section, is decoded by a decoder and is outputted by an output control section. Attribute information such as copyright information and a presentation time which corresponds to this attribute information are extracted by a copyright-information acquisition section, and a table in which these are recorded is created by a copyright-information management section. Then, at a specific time which is indicated by the presentation time that is recorded in the table, the attribute information which corresponds to the presentation time is reflected in an output of the presentation data by a playback-mode control section and the output control section.
